How come there's a Teflon Products and PVDF long lead times

Throughout the last year, the industry has had more difficulties than I have come across inside my thirty years experience. In the past I have seen sharp price increases, and I have witnessed several shortages, and delivery problems as a result of plastic resin allocations coming from plastic resin manufacturers. This is actually the very first occasion I have seen all these issues at one time.

PTFE Rod (TFE) and PVDF are both on allocation.

The two of these resins are in short supply. The  PTFE Sheet suppliers product PTFE (TFE) and Kynar  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide demand for this mineral has increased significantly, and the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is used within a great deal of purposes from non-stick fry griddles to ptfe tape for personal use. This specific mineral is a important raw material inside the production of fluoropolymers, fluorolubricants and many refrigerants.This escalating demand coupled with shortage of raw materials is responsible for a dramatic price increase (almost double during the last year), shortages, and we expect these two factors to keep at it in the near future.
